asterisk users - Dec 2003 - Configuring new system for a non-profit organization

Hi,

The PBX at the Colorado Organization for Victims' Assistance fried as a 
result of the building power being cycled.  I'm now in the process of 
building an * system to replace the failed PBX.  Minimum cost is the 
priority.

I have a T100P card installed in the new system, and I am about to order 
integrated T1 services from the "CBeyond" company.  They will require 
eight voice channels and at least eight data (they presently have DSL.) 
  The rep. says that for the same cost ($520/mo) they will get all 24 
channels as data--the channels are dynamically allocated.  As each voice 
call is initiated, a channel will be pulled from data and used for voice.

Can the T100P handle this dynamic allocation?  Or must the channels be 
fixed?

Thank for your help,
Michael Welter

Michael, unless Cbeyond is doing something different now, they provide a
Cisco IAD as part of their service.  The IAD has an Ethernet port for your
Internet connection and POTs ports to connect to your PBX.  My guess is
that you will have to put a channel bank between their IAD and your T100P.

By the way we had the Cbeyond service and it worked very well.

Hi Mike,

The magic question to ask CBeyond is whether the T1 they provide you is
Primary Rate Interface (PRI) or Basic Rate Interface (BRI).  Their web
site is too heavy on pretty marketing and waaaay short on technical
details.  PRI gives you _23_ channels with a digital control channel
whereas BRI gives you 24 channels but with more basic (primative)
control.

Actually, its PRI or RBS (Robbed Bit Signalling)  BRI is a 2 B channel +
1D channel ISDN interface
